Test: Moments - Question 1

What is a moment?

Detailed Solution for Test: Moments - Question 1
Moments can be used to your advantage when using a lever
Test: Moments - Question 2

What is the formula for the size of a moment?

Detailed Solution for Test: Moments - Question 2

This is a direct proportionality so if the force is greater, the moment is larger. If the distance is longer, the moment will be larger too. The opposite is true for smaller values of both terms of the equation

Test: Moments - Question 3

If an object is not turning, the total clockwise moment, compared to the total anti-clockwise moment about any pivot, must be what?

Detailed Solution for Test: Moments - Question 3
For an object to be at rest on a pivot, all the forces acting on it must be in equilibrium
Test: Moments - Question 4
A see-saw is balanced on a pivot with two children on it. One child is sitting 1.5 m to the left of the pivot and has a mass of 50 kg. Another child of mass 30 kg is sitting on the right hand side of the pivot. What distance away from the pivot is the child on the right of the pivot?
Detailed Solution for Test: Moments - Question 4
The key word in the question is balanced so the principle of moments calculation can be applied
Test: Moments - Question 5
What is the force that creates a moment of 10 N m when it is applied 0.25 m from the pivot?
Detailed Solution for Test: Moments - Question 5
Rearrangement of the equation for calculating the size of a moment
Test: Moments - Question 6
If the point of application of the force was moved further away from the pivot, what would be the effect on the moment?
Detailed Solution for Test: Moments - Question 6
Changing either (or both) of the force and distance will alter the moment. An example of this would be using a spanner to turn a nut. A longer spanner enables you to apply the force from a greater distance, increasing the moment and magnifying the force that your muscles can apply
Test: Moments - Question 7

Which of the following scenarios describes a moment in physics?

Detailed Solution for Test: Moments - Question 7

A moment refers to the turning effect of a force around a pivot point.

Test: Moments - Question 8

What happens to the moment if both the force and the distance from the pivot increase?

Detailed Solution for Test: Moments - Question 8

Moment (M) is calculated as M = F × d. Increasing either the force (F) or the distance (d) increases the moment.

Test: Moments - Question 9
Which of the following is an example of the principle of moments being utilised?
Detailed Solution for Test: Moments - Question 9
The crowbar is being used as a lever. Levers are a favourite of the examiners for testing your knowledge of moments
Test: Moments - Question 10

What is the condition for an object to be in rotational equilibrium with respect to moments?

Detailed Solution for Test: Moments - Question 10

For an object to be in rotational equilibrium, the sum of clockwise moments must equal the sum of anti-clockwise moments about any point or pivot.
